Abstract (en)

[origin: EP1047041A2] Pairs of scanning electrodes and sustaining electrode are covered with dielectric layer. Data electrodes are arranged orthogonal and in opposition in discharge space. During initialization period initialization voltage waveform is applied to scanning electrode. During write period, voltage of opposite polarity is applied. Selected data electrodes are sequentially supplied with waveform of same polarity as initialization waveform. Potential of scanning electrode is set lower than that applied at end of initialization.

[origin: EP1047041A2] A method of driving an AC plasma display panel is provided, in which plural pairs of a scanning electrode (2) and a sustain electrode (3) covered with a dielectric layer (4) and a plurality of data electrodes (8) are arranged orthogonal to and opposing each other with a discharge space (11) being sandwiched therebetween. The method includes an initialization period for applying, to the scanning electrode, an initialization waveform of a ramp voltage and a write period for applying, to the scanning electrode, a scanning waveform with a polarity opposite to that of the initialization waveform sequentially and at the same time applying, to the selected data electrodes, a data waveform with the same polarity as that of the initialization waveform. The potential of the scanning electrode to which the scanning waveform is being applied is set to be lower than that of the scanning electrode at the end of the application of the initialization waveform. In addition, the potential of the sustain electrode during the application of the scanning waveform is set to be lower than that of the sustain electrode at the end of the application of the initialization waveform. <IMAGE>
